摘要
在相同施氮水平下,研究了基肥、蘖肥、穗肥、粒肥的不同配比对水稻生长发育及产量的影响。结果表明,氮肥配比对水稻分蘖、成穗率、株高、干物质积累、每穗粒数、结实率、产量等方面的影响差异达到显著或极显著水平,并在不同品种上表现不一致,耐肥高产品种当穗粒肥比例达到总氮量的40%时有利于高产的形成,而基蘖肥比例达到总氮量的70%时更适合优质水稻品种栽培。
The effects of growth development and yield of rice basic fertilizer, tillering fertilizer, earing fertilizer, granular fertilizer were studied under the same nitrogen application level. The results indicated that effected difference of fertilizer ratio on rice tiller, percentage ofcarbearing tiller, plant height, dry matter accumulation, number of grain per ear, maturing rate and yield reached significant level or extremely significant difference, and manifested ineonformity on different varieties, it was good for high yield when earing and granular fertilizers occupied 40% of total nitrogen for fertilizer varieties, while it was fit for cultivation high quality rice when basic and tillering fertilizers occupied 70% of total nitrogen
